Why does every window close

Hi,

Getting the same issue here.

Problem becomes quite big when a popup comes out to fill in some specific information and automatically closes ALL WINDOWS once the info is selected (Salesforce.com happens to use that method for filling in certain fields). This means I have no way of actually entering the info required.
Even worse, if I try to merge the windows by getting the tabs from one and putting them under another, Brave also closes all windows.

I’m using version Version 1.31.91 Chromium: 95.0.4638.69 (Official Build) (64-bit).

Please help
